Abstract：
:Induction of anaphylactic shock in mice by i.v. antigen challenge (bovine serum albumin, 100 micrograms) or i.v. treatment with the mast cell degranulator compound 48/80 resulted in 80 and 90% mortality rate, respectively. Inhibition of nitric oxide (NO) synthesis from L-arginine by co-injection of the L-arginine analog NG-nitro-L-arginine methyl ester (L-NAME, 30 mg/kg) reduced the mortality rate by 40 and 20% in the antigen- and compound 48/80-induced shock models. Treatment with 60 mg/kg L-NAME reduced the mortality rate by 60% in these shock models. This beneficial effect was reversed by addition of L-arginine (120 mg/kg) but not D-arginine (120 mg/kg). These results suggest NO production as a possible mechanism involved in the pathophysiology of anaphylactic shock.
